Last Battery review

Our take

A digital guide about batteries and backup power, sold with a long video. The video promises a lot (“cancels your power bills”). Treat it as a hands-on DIY project book, not a way to stop paying for power. Only for people who are comfortable and careful with electrical work.

What you get

  • A downloadable guide on batteries, backup power and related DIY projects.
  • Instant access after payment through ClickBank.
  • The seller's own disclaimer lists procedures with batteries, chemicals and electrical parts.

What to be careful about

  • The sales page is a long video with no written list of contents, so it is hard to check what you get before you buy.
  • Claims about cancelling power bills are marketing. Results depend on your home, your climate and your equipment.
  • The order form adds a $17 extra (“Power-Tool Side Hustle”). Untick it if you do not want it.
  • Batteries and chemicals can cause burns, fires or shocks. The seller says so in its own disclaimer. Follow local electrical rules.

Good fit if

You like DIY electrical projects, you have a safe place to work, and you want a backup power project for outages.

Skip it if

You want lower bills without hands-on work, or you are not comfortable working with batteries and wiring.

Refunds and payment

Last Battery is sold through ClickBank, a US online retailer, by Big Moves DTS Inc. Your payment, receipt and refund request go through ClickBank, which normally accepts refund requests for 60 days. Keep your receipt email, which has the refund link.

How we reviewed it

We watched the sales page, read the order form, the seller's terms and disclaimer, and checked how refunds work. The seller does not publish a table of contents, so this review covers what can be checked before you buy. If you bought it, tell us how it went and we will update this review.
